ABSTRACT:
An automotive suspension system including a suspension cylinder installed between the automobile frame and the control arm of the automobile wheel; a hydraulic apparatus including two corresponding hydraulic cylinders each cylinder having a combination of a piston and a piston rod; a combination coil-spring and shock absorber member sandwiched between the two piston rods of the cylinders and being compressed thereby; and a control device for directing the flow of the hydraulic fluid from the suspension cylinder to either of the two cylinders. One of the cylinders has a sectional diameter which is larger than that of the suspension cylinder and the remaining cylinder has a sectional diameter which is smaller than that of the suspension cylinder. As the result of the effect provided by the control of the control device of the suspension system, an automobile using it will provide a good cushioning effect to the user(s) thereof and will minimize the risk of overswing or flipping when making a turn.
